COMBING-MACI-IINE.

Specification of Letters Patent.

Patented Sept. 7, 1909.

To all whom it may concern: I

Be it known that I, JAMES SOU HWELL, of the city and county ofProvidenceand State of Rhode Island, haveinvented certainnew and usefulImprovements in 'Combing-Machines; and I do hereby declare the followingspecification, taken in connection with the accompanying drawings,forming a part of the same, to be a full, clear, and exact descriptionthereof.

The invention relates to circle combs of the type commonly known as theNoble comb, in which there is a large circle comb and two small circlecombs with two sets of drawing-off rolls for drawing OK the fibers ofwool from the large circle comb at opposite points, and with one set ofdrawingolf rolls for drawing 0]? the fibers from each of the smallcircle combs. I

Ordinarily each set of drawing-off rolls comprises two rolls bothfluted, but only one of which is positively driven, an endless apronbeing employed which passes between the two rolls and around thenon-driven roll and one or more other idler rolls. With sucharrangement'much difliculty has been experienced, if the sliver happensto break, in the liability of the broken end of the sliver being takenup by and wound upon the exposed positively driven roll. As said roll isnecessarily arranged in close proximity to the teeth of the comb, thewinding up of the sliver thereon speedily results in a jamming orbending of such teeth and a se-; rious damage and" injury to'themachine; Attempts have heretofore been made to prevent this winding upof the broken sliver upon the drawing-off roll and the damage resultingtherefrom by providing a third fluted roll loosely mounted in proximityto the drawing-off rolls and adapted to be rotated by frictional contactwith the apron, the idea being that such third loosely mounted rollwould serve to lead the sliver away from the exposed drawing-off roll.It has been found in practice, however, that the employment of suchloosely mounted third fluted roll. isineffectiveto produce the desiredresult, and that said third roll,-instead of always leading the sliveraway from the exposed positively driven roll, frequently operates tocarry the broken end of the sliver to such positively driven roll, andsothat it will be wound up thereon, with resulting damage and injury tothe comb, the same as when such third roll was not employed.

The present invention consists primarily in the employment, inconnection with the pair of drawing-off rolls and endless apron, of athird roll located on the delivery side ofsaid drawing-off rolls and inpositively driving said third roll, but at a slower speed than thepositively driven drawing-off roll and endless apron are driven.

A further feature of invention consists in making this third positivelydriven roll plain instead of fluted, said plain roll being likewisedriven at a slower rate of speed than the drawing-off rolls and endlessapron.

Referring to the drawings, Figure 1 is a plan view of a wool-combingmachine of the type referred to showing the arrangement of the combs,the drawing-off rolls and the endless aprons, and showing my inventionapplied thereto. Fig. 2 is a plan view on a larger scale of a bracketfor supporting the third roll in position and showing the arrangement ofgears for driving said third roll. Fig. 3 is a side view, partly insection, of said bracket with the third roll mounted thereon.

1 represents the large circle comb and 2, 2, represent the two smallcircle combs.

8 and 4 represent the drawing-off rolls for the large circle comb, 3being the positively driven roll and 4 being the loosely mounted roll.

5 and 6 represent the endless aprons for conducting the slivers from thelarge circle comb to join the slivers from the small circle combs. 1

The liability of breakage of the sliver exists chiefly, if not entirely,in the case of the slivers from the small circle combs, and in thedrawings the invention is shown only in connection with the drawing-offrolls for the small circle combs. If desired, however, the invention mayalso be employed in connection with the drawing-off rolls for the largecircle comb. As the construction is the same in the case of thedrawing-01f rolls for each one of the two small circle combs,

it will be sufficient to describe said constructlon 1n COHIIGCJLIOH w thone set of such drawing-off rolls, the several parts being designated 1nthe drawings, however, by the same reference numerals 1n the case ofboth sets of such drawing-off rolls.

' 10 rigidly mounted in the adjustable bracket ll. This bracket 11 isadjustably secured to a fixed part of the machine by means of aclamp-bolt. 12 taking into the slot 13 formed in said bracket. By thisconstruction the position of the roll 9- with relation to the roll 7 andthe apron 6' may be readily adjusted. In the drawings the roll 9 is forout of contact with the sliver. It will be understood, however, that inthe ordinary operation of the machine the roll 9 to be so adjusted as tohe in contact with the sliver and preferably so as to produce more orless nip on the sliver between said roll and the apron. and therebyserve to draw the sliver away from the roll- 7.

The drawing-oft roll 7 is positively driven by suitable gearing (notshown)- inthe usual manner. The third roll 9 may be driven by anysuitable means which will impart to said roll a speed slower. than thespeed of the drawing-off roll 7 and of the endless apron 6, the speed ofsaid apron being the same as the speed of the roll 7 Inthe drawingstheroll 9 is shown as driven fi'om I the-gear It of the small circle comb.Said roll 9 is provided at its lower end with a gear 15-, which mesheswith a gear 16 loosely mounted on a stud 17 secured toan arm 18 of thebracket 11, said gear 16. in turn meshing with the gear 14 of the smallcircle comb. The ratio of these several gears: is to be such thatthe-roll 9 will be revolved at a slower speed than the speed of the roll7 and the endless apron 6.

7 With the construction above described the operation is as follows:With the roll 9 properly adjusted with relation to the roll sliver, asit leaves the apron 6, passes besliver, instead of being, caught up byand 'apron 6.

wound upon the drawing-off roll 7, will be carried along between theroll 9 and the surface speed of said apron is greater than the surfacespeed of the roll 9, the broken end of the sliver, instead. of beingcaught up prevented from being carried by the roll 9 on to the roll 7and being wound thereon. The broken end of the sliver, after being 9represents a third roll, 7

led away from the rolls by the apron, will drop down where it will do noharm, even if the breakage of the sliver should not be promptlydiscovered and the machine stopped.

W hil'e it is preferred that the roll 9 shall be a plain-surface roll,this is not absolutely essential, as substantially beneficial resultsmay be obtained even if said roll is roughened or fluted. \Vith the roll9 thus roughened or fluted, however, it has been found that there ismore or less tendency of the roll 5 to. back up. the sliver between theroll 9 and the roll 7, and it is for this reason that it is preferred toprovide the roll 9 with a plain smooth surface.

\Vhat I claim as my invention and desire to secure by Letters Patent is:convenience shown in an ad usted position 1. In a combing machine, thecombination. of apair of drawing-off rolls, an apron driven by one ofsaid rolls, a third rolllocated on the delivery side of said drawingoffrolls and adapted to prevent the winding of a broken sliver upon one ofsaid drawing-off rolls, and means for positively rotating said thirdroll independent of the apron.
